Lisa Marie Presley’s 8-year-old twin daughters have been removed from their parents’ custody by the Los Angeles County Department of Children and Family Services after the singer claimed to have found “disturbing” photos and videos of children on estranged husband Michael Lockwood’s computer.

E! News reports that these findings were brought to light after Presley opposed Lockwood’s request for spousal support in the divorce proceedings.

According to court documents pertaining to the couple’s divorce that were obtained by The Daily Mail, Presley stated that she was “shocked and horrified and sick to my stomach” regarding the findings. She revealed in the documents that police in Beverly Hills discovered 80 devices belonging to Lockwood during a raid on her home, which have yet to be analyzed.

The documents further reveal allegations of sexual abuse and neglect against the guitarist that are set to be addressed in a trial in Los Angeles’ Edmund D. Edelman Children’s Court in March.

“I have no idea what else may be on those devices and fear that there are more and worse images and evidence in these un-analyzed devices,” Presley states in the documents.
